To all whom it may concern:

Be it known that I, HOMER E. BARNT- HOUSE, a citizen of the UnitedStates, residing at Marion, in the county of Marion, State of Ohio, haveinvented a new and useful Auxiliary Valve for Internal-CombustionEngines; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to the art of valves and the like, and moreparticularly to a new and useful valve especially adapted for internalcombustion engines for supplying additional air to the intake manifoldto mix with the charge passing therethrough.

Another object of the invention is the provision of means for regulatingthe amount of additional air.

.Another object of the invention is to dispose the. valve operatinghandle in such position as to prevent the same from being in the way.

One of the features of the invention is the provision of a memberthreaded into the intake of the valve and provided with oppositelydisposed yieldable parts or prongs, whereby, as the member is adjustedinto and out of the inlet of the valve, said opposing prongs will movetoward and from each other to regulate the amount of additional air.

In practical fields. the details of'construction may necessitatealterations falling within the scope of what is claimed.

The invention comprises further featuresand combination of parts, ashereinafter set forth, shown in the drawings and claimed. 7

Referring more especially to the drawings, l designates an intakemanifold of an internal combustion automobile engine, and 2 denotes anauxiliary valve casing. The valve casing 2 has a threaded extension 3,which is threaded into the wall of the manifold, as shown. The valvecasing is provided with an intake passage 4, through which an auxiliarysupply of air may pass, in order to enter the intake manifold. Formed inthe casing 2 and at right angles to the passage 4 is a conical opening5. for the reception of the tapering plug valve 6, on to an extension 7of which. a suitable washer Sis fitted. A screw 9 is threaded into thesmaller end of the plug valve, and interposed between the head, of thescrew 9 and sa d washer 8, is a plate 10, thereby holding the washer 8closely in engagement with the valve casing. By setting up on the screw9, the plug valve 6 may be tightened in its opening 5. The tapering plugvalve is provided with a transverse opening 11, which may register withthe passage 4, whereby an extra supply of air may pass therethrough andinto the intake manifold. The valve casing 2 is provided with a chamber12 adjacent that portion of the passage 4- nearest the intake manifold,and into th s chamber 12, this additional air may collect. As theopening 11 begins to gradually register with the chamber 12. as thevalve- 6 is opened or gradually adjusted toward an open position. theadditional air gradually increases. and when the valve 6 is gradually.closed, the additional air is gradually decreased. By means of thisadditional air into the intake manifold. the charge from the carbureterto the engine is additionally volatilized or vaporized, and under theseconditions the carbureter requires less fuel. The larger end of thevalve is provided with an extension 13 terminating in a flat part 14.through an aperture 15 of which, the angled end 16 of the valveoperating rod 17 is disposed, there being a cotter pin 18, to hold theangled end in place. The other end of the rod 17 terminates in a handle19. By turning the rod 17 in one direction or the other, the taperedplug valve 6 may be rotated in one direction or the other to cause theopening 11 to register with the chamber 12 and one end portion of thepassage 4, so'that an additional iupdply of air may enter the intakemani- In Figs. 4, 5 and 6, the valve casing 2 has its extension 20interiorly threaded, as shown at 21, and which threaded interior islarger in diameter than the passage 4. Engaging the threads of theinterior 21 is a plug or member 22, which is provided with oppositelydisposed yieldable prongs 23. The outer faces of the prongs 23 are soinclined as to cooperate with diametrically opposite sides of thepassage 4, as shown at 24, ad jacent the shoulder 25, in order to causethe prongs to move toward and from each other, whereby the additionalsupply of air may be decreased or increased. In other words, when thevalve 6 is adjusted, whereby the maximum supply of additional air isadmitted, the plug or member 22 may be adjusted, so that the prongs ormembers 23 will move toward and from each other, in order to regulatethe maximum supply of air. The plug or member 22 is provided with a pairof diametrically opposite projections 26, to be engaged by a spannerwrench, whereby the plug or member 22 may be adjusted. In Figs. 4 and 7,the valve operating rod consists of two sections, a.

valve engaging section 27 and a tubular handle section 28, whichtelescopically receives the section 27. A spring blade 29 is secured bya screw 30 to the tubular handle section- 28, and extending from theblade 29 is a lug 31 passing through an opening 32 in the wall of thetubular handle section.

This lug 31 enters an elongated groove 33' the valve, in order to holdthe handle section out of the way.

ing in an enlarged chamber adjacent the tapering opening, the passage ofthe other extension having its outer end portion enlarged which isinteriorly threaded and provided with an interior annular shoulder, atubular bushing member adjustably threaded into the enlargement of thepassage of the second extension, one end of said bushing member beingconical said conical portion being bifurcated substantially its fulllength, thereby causing to be formed opposite yieldable prongs extendinginto the small part of the passage last mentioned, the outer curvedportions of the prongs being adapted to contact with the smaller part ofsaid passage, whereby, as the bushing member is adjusted, said prongsmay be moved toward or from each other for regulating an extra supply ofair said enlarged portion of said passage adjacent said shoulders actingas a chamber for the collection of the air as it passes through thebushing member, the bushing member at its outer end having means to beengaged by an operating device for adjusting the bushing member, atapered plug valve in'said tapered opening and provided with atransverse opening; to cooperate with said axially alined passages toadditionally regulate a supply of air, and adjustable means foroperating the tapered plug valve.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
